[Local experimental infection caused by S. epidermidis sensitive to penicillin under the action of the antibiotic and acridines].

S. epidermidis D-5/48, D-5/240, and S. aureus 209 P caused a local infectious process with an analogous course in intrascrotal infection of male albino mice; this process was characterized by the changes of the relative weight coefficient of the affected tissues, positive staphylococcus culture, and exudative inflammation.

[Elimination of penicillinase plasmids by the new acridine derivative, Dimer].

The possibility of eliminating the drug resistance determinants in penicillinase-producing staphylococci under the effect of an acridine "dimer", synthesized by French scientists was studied. Comparison of the eliminating activity of a number of acridine compounds, such as acrichin, acriflavine, proflavine and "dimer" showed that the new derivative of acridine as well as the other acridines used in the experiments induced elimination of the penicillinase plasmids when used in the sublethal concentrations.

[Staphylococcal plasmacoagulase. III. Use of thrombelastography to study the properties of extracellular staphylocoagulase].

A method of thromboelastography was applied to the study of the influence of supernatents of the S. aureus and S. epidermidis culture fluid on the process of blood coagulation.
